Estimated Effort: 4-6 Engineering Days

“Estimated effort: 4-6 engineering days for the requested screens."

Quick anecdote: Marcelo, is still improving the game we built together. He released v2 this morning, and his next update is keyboard support for accessibility. He asked Codex to estimate the work required, and the response was a good reminder of how fast the product lifecycle is changing.

“Estimated effort: 4-6 engineering days for the requested screens. Add 0.5-1 day if you want full keyboard parity for the lobby’s Customize Piece and color-picker subflows now.”

However, when he told Codex to implement it, the first pass took less than five minutes, and required minimum changes before it was ready for use.

That is what collapsing development speed looks like.
